Thanks for the info. I will look around and change out for the spring start-up. Any reason to add the zink additive now for the winter storage?

I appreciate all of the wisdom, care and attention this forum shares as I wish not to damage this piece of family history...that also needs to pull some skiers as it was built to do!

staying with 6-volt system and wondering if "original" fuse panel is safe or should I upgrade?

John,
The fuse panel is not original. They weren't fusing any electrics back then. Why do you feel it's unsafe? If anything, it makes the boat safer. Keep it.

BTW, for those of you who are ACBS "naysayers", adding fusing is NOT a point deduction in a judged show.

Thanks Pete,

That would explain why a closer look reveals turn signals, heater/AC ect.... looks like it car off a car panel.

John,
It's not a panel off a car. It's a Stewart Warner marine panel.

EDIT:
John,
Sorry, I misunderstood your post. I was too focused on the gauge panel. Yes, the fuse panel could have been made for a car but as mentioned, the gauge panel is a Stewart Warner.

Boat update:
1956 Atom was launched last week with several days of cruising around Silver Lake, Michigan. We even pulled up my 18 yr old son up on 2 and dropped 1). More adjustments I am sure will come as she tops out at 2500 RPM's at this time. Thanks for all the help on this project.

John,
You should be getting at least another 1000 RPM. What prop (dia. and pitch) is on the boat? Have you set the timing? Setting the timing on the old flat heads is easy. All you need is two people. One at the helm giving it full throttle and the other at the distributor. You turn the distributor till you get max RPM and back it off slightly.

No pictures of your boat from the top of the sand dunes? Silver Lake is beautiful. Good luck with the Atom.

Will check props when back up at the lake later this month. I did try to adjust timing as described, but no higher than 2500.

Any one near the Silver Lake Sand Dunes area from July 27-Aug 4th are welcome to stop by for a beer, some tinkering on the engine, a ride on the lake and I have a Jeep we can hit the dunes with.

Thought I would give an update on the 56-Atom. After a great first summer of cruising at sub-rpms of 2500 which was good-enough, I went back to tinkering on things. We checked everything and applied all recommendations from the forum group, change of props, timing, fuel intakes, air, carburetor linkages, jets...thank you!

On the day that was to be the last run of the season...met an older gentleman at the boat launch who offered to take a look. He immediately ID the issue as a weak breaker arm spring. I adjusted it with a slight bend via needle nose pliers and we ran it up to 3000rpms. Adjusted timing (which is pretty fun with my daughter at the helm running wide open down the lake with one hand on the ski pole and the other on the distributor cap) ...with no improvement.

Back at the garage...replaced breaker arm spring, adjusted points .020 and talked my wife into doing one more run for the season...and to our excitement, we watched the RPMs tac up to 3400 which is max per manual. A wave runner clocked us at 32 mph. Felt exhilarating and hoped the old plywood would hold together!

Have put her to bed for the season and look forward to making her "more original" for some shows next summer as well as getting to a reunion or two.   I think the FB link covers most of the steps in the restoration that began in 2012.

Thanks to the CCF community, you have been a major part of getting the 1956 back up to speed!
